Accelero L7 – Exclusive ARCTIC COOLING Solution for SAPPHIRE

(Auszug aus der Pressemitteilung)

Pfäffikon/Switzerland,1 September 2009 – SAPPHIRE Technology, the leading manufacturer and global supplier of ATI/AMD based graphics solutions is equipping two of its new product lines with exclusive near silent cooling solutions developed specially by Swiss cooling solution provider ARCTIC COOLING.


The new cooler known as Accelero L7 was developed in an OEM project by ARCTIC COOLING exclusively for SAPPHIRE. It is already being employed on the newly-launched model SAPPHIRE HD 4770 and the latest version of the SAPPHIRE HD 4670.

A Truly SAPPHIRE Cooler
The Accelero L7 was designed in the shape of a gem, resonating with the brand of SAPPHIRE.

“We are pleased to have further collaboration with SAPPHIRE,” said Magnus Huber, managing director of ARCTIC COOLING. “When we designed the Accelero L7 for the company, we thought a gem shape would integrate well with their brand.”

“The Accelero L7 has a very stylish look and offers nearly inaudible cooling to the SAPPHIRE HD4770 and HD4670 graphic cards,” he continued. “With significant GPU temperature reduction, the Accelero L7 can extend the service life of these valuable cards, as well as to boost their overclocking and graphic performance to a new level.”

“SAPPHIRE has always been a leader in Silent Cooling,” said Bill Donnelly, Global PR Director for SAPPHIRE. “We are very happy to work with partner companies like ARCTIC COOLING who can bring us state of the art solutions that allow us to deliver highly efficient graphics products that give great value to our customers”

Highly efficient cooling for high quality graphic cards
Just like other ARCTIC COOLING products, the Accelero L7 was developed using the latest fluid analysis software and numerous simulations, which guarantee efficient and quiet thermal management at all time.

The optimised heatsink of the Accelero L7 comes with the pre-applied thermal compound ARCTIC MX-2. This reputable TIM gives a perfect conjunction between the core and the heatsink that reinforces the overall cooling performance. The Accelero L7 also features a patented fan holder and low noise impeller in the 92mm PWM fan, achieving high airflow at a lower fan speed. As a result, core heat is dissipated efficiently from the heatsink and the fan, which makes the Accelero L7 a superb cooling solution for Sapphire HD 4770 and SAPPHIREHD 4670 graphic cards.

The Accelero L7 is designed with an excellent acoustic concept. Friction from rotation is greatly reduced by a fluid dynamic bearing. Together with the PWM function, the Accelero L7 delivers quiet cooling at all time – reaching a noise level of only 0.4 sone at full load.

The original SAPPHIRE HD 4770 was the first card in its class to use GDDR5 memory and was based on the first ever GPU built in 40nm process technology, but was quickly sold out. The new model is a SAPPHIRE original design based on the same GPU and the special cooler built exclusively for this product by ARCTIC COOLING. The new SAPPHIRE HD 4770 also features native HDMI, VGA and DVI connections on the rear bracket, supporting a wider range of displays without the use of adapters.

The SAPPHIRE HD 4770 uses the powerful graphics architectures from the ATI division of AMD, incorporating multi-purpose stream processing units and improved memory management architecture. With 640 stream processors – twice as many as previous generation mid-range cards – and core clock speed of 750MHz, together with 512MB of GDDR5 memory clocked at 800MHz (3200MHz effective), the SAPPHIRE HD 4770delivers stunning performance for gaming or image rendering at a mid-range price.
